Abstract: 1,167,376. Feeding and rewinding webs. STRACHAN & HENSHAW Ltd. 29 Feb., 1968 [31 March, 1967], No. 14908/67. Heading B8R. Web feeding and rewind apparatus comprises a reed stand 10 having at least three web-roll supporting stations and means for driving each web-roll individually in either direction. When the supply roll 4 nears exhaustion, the reel stand is indexed anti-clockwise to bring a replacement web-roll 12 into the supply station where it is accelerated up to the speed of the running web (Fig. 2). A knife 13 and splicing roller 14 are subsequently operated to cause cut-off and transfer dependent upon the number of turns on the old supply roll 4 and the next passing of a magnetic tape 15 depicting the leading edge of the new web on supply roll 12. The old supply roll 4 is then rotated in the opposite direction up to the speed of the web 5 being wound on take-up roll 7. The tail left after the cutting by knife 13 is wrapped back on to the roll 4, and as it does so a paste applying roller 16 is brought in so that the radially outer face of the tail is covered with adhesive. When the speeds of the web-roll 4 and web 5 match, a splicing knife 17 and roller 18, operate to sever the web 5 and splice it to the web-roll 4 now acting as a row take-up roll. The completed web-roll 7 is then replaced by a new supply roll in readiness for the next cycle of operations.

Title: Improvements in and relating to methods of manufacturing memory arrays
IPC: H01F10/20
Filed: 1961-04-26
Abstract: 924,848. Magnetic storage devices; magnetic structures. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 26, 1961 [May 27, 1960], No. 15055/61. Class 38 (2). [Also in Group XXXIX] A magnetic memory array comprises a magnetic material secured to an inert substrate by spaced particles of an inorganic material preferably of the same composition as the magnetic material. The substrate may comprise platinum or palladium or a ceramic such as Mn 2.8  Ti 0.1 Fe 0.1 O 4  and Mn 2.0 Ti 0.1 Al 0.9 O 4 , on which is applied layers of a parting sand in the desired configuration of the array. The parting sand consists of volatile organic constituents and a small percentage, e.g. 1 % or less by weight, of a non-volatile inorganic ferrite material, the sand being applied to the substrate through a suitably masked silk screen. A suitable sand composition is stated to be 2.5 g. carbon black, 1.25 g. ethyl cellulose, 23.75 g. pine oil, 2.0 g. varnish and 0.1 g. Fe 1.68 Mn 1 . 25 Cr 0.06 Ni 0.03 O 4 . The same ferrite material is used for the magnetic storage elements, and is applied in ink form by a silk screen process on to a treated glass slide which has been previously coated with a 2% gelatin-water solution and a solution of 3 grams of ethyl cellulose and 40 grams of pine oil. When dry, the slide is dipped in water to dissolve the gelatine. The pattern thus produced is placed over the parting sand and is initially heated to 500 ‹ C. to drive off the binder constituents. The temperature is then raised to 900‹ C. to burn off the carbon, and final firing takes place at 1400‹ C. for 15 minutes to several hours to complete the process, the ferrite storage elements so formed being bound to the substrate by separate sintered particles of the same material. In a modification, tubular storage elements are formed by positioning the parting sand 2, Fig. 6, and memory element pattern 7 in semi-circular grooves of a substrate 8, and after placing the two substrates in facing alignment, as shown in Fig. 7, the ferrite portions are sintered together by the heating operation.

Filed: 1946-05-23
Abstract: The resistance to mechanical and chemical attack of freshly exposed surfaces of articles comprising a polymer of a lower alkyl or aryl ester, amide or nitrile of an a -halogen acrylic acid is increased by heating to 60-140 DEG  C. without substantial softening under at most normal pressure for 1-72 hours.  The treatment may be carried out in a container which, if desired, may be sealed, and preferably is kept filled with inert gas, e.g. nitrogen, carbon dioxide, or is under vacuum during heating.  Examples of the heat treatment of articles of polymethyl a -chloracrylate are given, other suitable articles comprise polymers of ethyl, propyl, butyl, phenyl, benzyl and cyclohexyl esters of a -chloro- and a -bromo-acrylic acids, a -chloro- and a -bromo-amides and N-substituted derivatives thereof; and a -chloro-and a -bromoacrylonitriles.  Resins which have been shaped or formed by drilling, filing, turning, sawing, milling, polishing and other machining operations into articles, e.g. optical lenses, prisms, windshields, cockpit covers and cupolas, and have had fresh surfaces exposed may be made resistant to scratching and to the action of solvents and abrasives by this process.  Sheets suitable for window glass substitutes and for blanks for lenses and goggles are made by evaporating the solvent from a solution of the resin in methylene or ethylene chloride, nitromethane, dioxane, chloroform, nitrobenzene, acetophenone, phenol, chloracetic acid or a -chloropropionic or a -b -dichloropropionic acids or their methyl and ethyl esters, followed by grinding, polishing, cutting to size and heat treating by the process of the invention.
